Amanda Knox was a 20-year-old college student from Seattle studying abroad in Italy when she was accused and convicted of killing her roommate Meredith Kercher, a student from England.
Prosecutors claimed that Kercher was killed during a drug-fueled night when a sex game went awry. Knox's then-boyfriend Raffaele Sollecito was tried with her and also found guilty. In a separate trial, Ivory Coast native Rudy Guede was also found guilty of murdering Kercher.
Knox and Sollecito maintained their innocence, however, and won an appeal this October that set them free.
